Betaine surfactants Sodium Diethylhexyl Sulfosuccinate CAS 1639-66-3
Betaine surfactants
It is produced by the reaction of fatty tertiary amines and salt chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the initial three and is presently the primary surfactant in child hair shampoo.
In 1940, the American DuPont Business invented and used this type of compound. Like amino acid surfactants, this kind of surfactant has strong detergency and low irritability, and the solution is weakly acidic. Animal experiments have actually shown that this type of substance is much less harmful. It is an optimal surfactant.

Amino acid surfactants
Made from a mix of coconut oil and amino acids, it is secure, mild, and non-irritating. The most crucial thing is that it is naturally weakly acidic and meets the pH requirements of healthy skin and hair. It is the perfect surfactant in baby shampoo. They are “cocoyl glycine,” “cocoyl glutamate disodium,” etc
From the viewpoint of chemical residential properties, its pH value is between 5.5 and 6.5, which is weakly acidic and near to the pH worth of human skin. Hence, it is mild and skin-friendly and ideal for all hair kinds; amino acid surfactants are zwitterionic and easily soluble in water. It is very easy to wash tidy.
Yet it additionally has limitations. Amino acid surfactants are numerous to lots of times more expensive than common surfactants, and a lot of are shampoos specifically produced infants and little ones. The drawbacks of amino acid surfactants are that they are not abundant in foam and have weak decontamination capacity.
The phenomenon of solidification and turbidity of surfactants in winter season is mostly as a result of the reduced temperature level triggering some of its components to crystallize or precipitate.

What if surfactant solidifies and ends up being turbid in wintertime?
This is a physical phenomenon and does not have a substantial influence on the efficiency of surfactants. In order to fix this problem, the following techniques can be taken:
1. Increase the temperature: Position the surfactant in a warm setting or raise its temperature level by home heating to make sure that the crystallized or sped up elements will progressively dissolve and the surfactant will go back to a clear state. Nonetheless, it must be kept in mind that the temperature level should be stayed clear of when warming to avoid impacting the surfactant’s performance.
2. Stirring: For surfactants that have strengthened or come to be turbid, they can be restored to an uniform state by mixing. Mixing can help taken shape or sped up active ingredients redisperse right into the fluid and boost surfactant clarity.
3. Include solvent: In many cases, an ideal quantity of solvent can be contributed to thin down the surfactant, thereby improving its coagulation and turbidity. Nevertheless, the added solvent must work with the surfactant and ought to not affect its usage impact.
